What are the key features of SFM-103-02-F-D-LC?
- 6-position dual-row SMT socket with 0.050" (1.27 mm) fine pitch, providing 12 female contacts in a minimal board footprint for high-density mezzanine or cable interconnect applications
- High-reliability socket strip construction with low-clearance (-LC) profile for reduced inter-board gap in stacked PCB assemblies and thin enclosures
- Dual-row female contact arrangement ensures even contact force distribution across all 12 positions, maintaining signal integrity in vibration-prone industrial and aerospace environments
What is SFM-103-02-F-D-LC used for?
The SFM-103-02-F-D-LC is designed for high-density mezzanine stacking, FPGA daughter card interfaces, and modular embedded computing platforms where fine 0.050" pitch dual-row socket strips with 12 contacts are required in a low-clearance SMT footprint. Its high-reliability construction makes it appropriate for medical imaging boards, military electronics, and space-constrained instrumentation requiring consistent mating performance over thousands of insertion cycles.

Frequently Asked Questions
What total contact count and pitch does the SFM-103-02-F-D-LC provide, and how does that compare to 0.100" pitch alternatives?
The SFM-103-02-F-D-LC is a 6-position dual-row socket with 12 female contacts at a 0.050" (1.27 mm) pitch. Compared to a 0.100" (2.54 mm) pitch connector with the same 12 contacts, the SFM-103-02-F-D-LC occupies approximately half the board length in the contact row direction, making it the preferred choice when PCB real estate is under 8 mm in one axis and a fine-pitch mating header is already specified.
What does the -LC (low-clearance) suffix mean for the SFM-103-02-F-D-LC, and which design scenarios benefit most?
The -LC suffix indicates a low-clearance socket profile that reduces the minimum board-to-board gap needed for mating to less than 5 mm. This benefits stacked PCB assemblies such as microcontroller carrier boards and display modules where maintaining a total stack height below 10 mm is required, and where a standard-height 0.050" pitch socket would exceed the mechanical clearance envelope of the enclosure.
How does the dual-row configuration of the SFM-103-02-F-D-LC improve signal routing compared to a single-row socket of the same pitch?
A dual-row configuration places 12 contacts in 2 rows of 6 at 0.050" (1.27 mm) pitch, which shortens the connector body length by 50% versus a single-row 12-position socket at the same pitch. This compact two-row layout allows the designer to allocate the saved PCB length to additional decoupling capacitors or shielding features directly adjacent to the connector, improving signal integrity on high-speed data bus lines operating above 500 MHz.
In which high-reliability application sectors is the SFM-103-02-F-D-LC typically specified over standard commercial socket strips?
The SFM-103-02-F-D-LC is specified in aerospace avionics, medical grade 2 instruments, and ruggedized military electronics where the connector must maintain reliable contact resistance below 50 milliohms across at least 200 mating cycles under vibration profiles up to 20 g. Standard commercial 0.050" pitch socket strips lack the contact retention and gold or tin plating consistency required for these applications, making the SFM high-reliability series the appropriate choice.
